Implementations of the fork–join model will typically fork tasks, fibers or lightweight threads, not operating-system-level "heavyweight" threads or processes, and use a thread pool to execute these tasks: the fork primitive allows the programmer to specify potential parallelism, which the implementation then maps onto actual parallel execution. [1]
A child process in computing is a process created by another process (the parent process).This technique pertains to multitasking operating systems, and is sometimes called a subprocess or traditionally a subtask.
The DOS/Windows spawn functions are inspired by Unix functions fork and exec; however, as these operating systems do not support fork, [2] the spawn function was supplied as a replacement for the fork-exec combination. However, the spawn function, although it deals adequately with the most common use cases, lacks the full power of fork-exec ...
A grid computing system that connects many personal computers over the Internet via inter-process network communication. In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system.
The POSIX-compatibility component of VM/CMS (OpenExtensions) provides a very limited implementation of fork, in which the parent is suspended while the child executes, and the child and the parent share the same address space. [19] This is essentially a vfork labelled as a fork. (This applies to the CMS guest operating system only; other VM ...
Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. [ 1 ] [ 2 ] The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them.
The goal here is to model processes that happen concurrently, like multiple clients accessing a server at the same time. Structuring software systems as composed of multiple concurrent, communicating parts can be useful for tackling complexity, regardless of whether the parts can be executed in parallel.
I'm not sure what the MVS equivalent to a fork/exec pair or to process_spawn(), i.e. a call that creates a new address space and starts a new task, running some program, in that address space, and doesn't cause the task executing the call to block until the new task terminates, would be.
